2 meter is now ready for use. Important Note: This is an air temperature probe only. DO NOT SUBMERSE IN LIQUID. DO NOT PLACE IN OPEN FLAME. This will damage the sensor board and void the warranty. Do not use in extreme cold or extreme hot temperatures (such as an oven or non-ambient environment such as carbon dioxide gas). Only use within the recommended ambient temperature range (-22 F to 140 F). 3. Display Console Layout Figure 1 1. Sensor probe. The humidity sensors are located inside this probe tip.

Glossary of Terms Accuracy Dew Point Hygrometer Term Range Wet Bulb Temperature Definition Accuracy is defined as the ability of a measurement to match the actual value of the quantity being measured. Dew Point is the temperature at which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation temperature. A hygrometer is a device that measures relative humidity. Relative humidity is a term used to describe the amount or percentage of water vapor that exists in air. Range is defined as the amount or extent a value can be measured. Wet Bulb Temperature reflects the physical properties of a system with a mixture of a gas and a vapor, usually air and water vapor. Wet bulb temperature is the lowest temperature that can be reached by the evaporation of water only. It is the temperature one feels when one's skin is wet and is exposed to moving air.
